【摘要】 研究一系列阳离子引发体系下的α－蒎烯均、共聚反应。发现ＡｌＣｌ＿３／ＳｂＣｌ＿３体系具有高引发活性，能得到分子过较高的α－蒎烯均聚物，聚合机理也不同于常用的ＡｌＣｌ＿３等Ｌｅｗｉｓ酸引发体系；与单独ＡｌＣｌ＿３引发相比，ＡｌＣｌ＿３／ＳｂＣｌ＿３能有效地引发α－蒎烯／苯乙烯的共聚合，两种单体的活性差缩小，共聚产物收率和分子虽提高。用臭氧化－层析联用法可达到分离α－蒎烯与苯乙烯的均、共聚物的目的。更多还原

【Abstract】 A series of Compound initiating systems for the homopolymerization and copolymerization of α-pinene were investigated.It was found that the AlCl₃/SbCl₃ had high aetivity and gave a resin with high moleculary weight, the polymerization mechanism was different from that of AlCl₃ .In the copolyme5ization,AlCl₃/SbCl₃ can reduce the differences between polymerization activities of α-pinenc and styine. The copoly-merization produets can be seprated primarily by the ozonization method.更多还原
